introduction groundwater resources in arid-semiarid zones universally suffer from problems of over-abstraction and declining water tables. in addition to the issues related to quantity, degradation of groundwater quality now assumes major importance in the arid and semiarid regions. in such areas, natural factors such as the low precipitation, combined with high evapotranspiration, result in hi...

[1] The inability to develop an accurate and precise parameter estimation method for catchment hydrochemical models has been a persistent problem. We investigate the use of multicriteria calibration techniques and the selection of the criteria as a first step in solving this problem. We applied a multicriteria search algorithm to the Alpine Hydrochemical Model (AHM) of the Emerald Lake watershe...

In this study multivariate statistical analysis are used to characterize relationships between hydrochemical properties ofthermal and non-thermal springs. Four factors for thermal waters and two for non-thermal springs were extracted basedon factor analysis. In thermal springs, the first factor showed high loading on Ca, Mg, Na and K and this factor wasinterpreted as leaching of cations in the ...

Analysis of hydrochemical behaviour during storm events can provide new insights into the process controls on nutrient transport in catchments. The examination of storm behaviours using hysteresis analysis has increased in recent years, partly due to the increased availability of high temporal resolution data sets for discharge and water quality parameters. A number of these analyses involve th...
